OBJECTIVE:To observe the clinical efficacy and safety of Shenmai injection combined with Trimetazidinee tablet in the treatment of hypothyroid heart disease. METHODS:64 patients with hypothyroid heart disease were randomly divided into control group and observation group. Patients in 2 groups were conventional treatment. Based on the treatment,control group was treated with Trimetazidine tablets 20 mg,orally,3 times a day;based on the treatment in control group,observation group was ad-ditionally treated with Shenmai injection 40 ml by intravenous infusion,once a day. The treatment course was 2 months. The clinic data was observed,including clinical efficacy,and T3,T4,TSH,LVEF,LVEDD and LVESD before and after treatment,pericar-dial effusion depth and incidence of adverse reactions. RESULTS:The total effective rate in observation group was significantly higher than control group(P<0.05). After treatment,T3 and T4 in 2 groups were significantly higher than before,TSH and LVESD were significantly lower than before(P<0.05),however,the difference was not statistically significant between 2 groups (P>0.05);LVEF in 2 groups was significantly higher than before,observation group was higher than control group,LVEDD and pericardial effusion depth were significantly lower than before,observation group was lower than control group(P<0.05). There were no obrious adverse reactions during treatment. CONCLUSIONS:Based on the conventional treatment,Shenmai injection com-bined with trimetazidinee has better efficacy than only trimetazidinee in the treatment of hypothyroid heart disease,with similar safety.

Objective:To study the feasibility of microarc oxide treatment on the enhancement of titanium-ceramic bonding strength. Method:Titanium samples in the size of 25 mm?3 mm?0.5 mm were prepared with smooth surface(group 1),rough surface(group 2) and microacrc oxide treated surface(group 3). Nickel-chromium alloy samples in the same size were prepared (group 4). The surface of the samples was observed by scanning electron microscope(SEM) and dispersive spectrometry analysis. Then, the samples were bonded to porcelain. The bonding interface was observed by SEM. The bonding strength of the samples was measured by a three-point bending test according to ISO 9693.Results:Microarc oxide treated surface was rough and porous. The interface of microarc oxide treated surface bonded to porcelain was compact. The bonding strength(MPa) of the samples of group 1,2,3 and 4 to porcelain was 30.79?1.3,36.12?3.03,45.84?3.15 and 48.35?3.06 respectively(group 3 vs group 1 or 2 P0.05). Conclusion:The microarc oxide treatment on titanium can increase the titanium-ceramic bond strength.

NH_4+ ion could be removed at temperature beyond 300 ℃.Conclusion: Calcium-deficient apatite has it's specific sintering character.

Objective To explore the effects of individualized nutrition intervention on body weight gaining and pregnant outcome in normal pregnant women. Methods Two hundred and twelve normal pregnant women admitted in our hospital before the 12th gestational week were divided into the observation group and the control group. Eighty-eight pregnant women admitted between October 2013 and January 2014 were assigned into the observation group and another 124 pregnant women admitted between June 2013 and September 2013 into the control group. The observation group was given nutrition assessment and nutritional guidance one by one and face to face by the nutritionist at three time points:around the 12 thgestational week, between the 22nd to 24th gestational week, and between the 32nd to 34th gestational week. The control group was given regular antenatal visits and lectures during pregnancy. These two groups were followed up until delivery. The comparisons were down between the groups in terms of body weight gain and complications during pregnancy, delivery mode and the change of perinatal fetus outcome. Results In the observation group, the body weight gaining of the pregnant women during pregnancy, the incidence of gestational diabetes mellitus (GDM) and the cesarean section rate were significantly lower than those of the control group (all P<0.05). The neonatal birth weight and the incidence of macrosomia were significantly lower than those of the control group (all P<0.05). Conclusion Individualized nutritional intervention given by the nutritionist can control body weight gaining during pregnancy, decrease the incidence of GDM, improve the pregnancy outcome and ensure the maternal and child health.

Objective To explore the effect of specific labeling method in improving the mixed placing of medical waste in neonatal intensive care unit(NICU).Methods Medical waste classification of 34 trash cans in the NICU of a hospital between July and December 2014 were investigated,July-September was pre-implementation phase of spe-cific labeling,October-December was post-implementation phase,mixed placing of medical waste between pre-and post-implementation phase was compared.Results A total of 504 cases of medical waste classification in NICU were investigated,252 cases respectively in pre-and post-implementation phase,74 cases of mixed placing were found. Mixed placing rates before implementing specific labeling was higher than after implementing (25.40%[64/252]vs 3.97%[10/252],χ2 =46.187,P <0.001 );before implementing specific labeling,57 cases of infectious waste and non-infectious waste were mixed placing,after implementing specific labeling,only 8 cases of infectious waste and non-infectious waste were mixed placing.Mixed placing were mainly performed by trainees for in-service training and interns,accounting for 39.06% before implementing and 50.00% after implementing.Conclusion The specific labeling for standardizing and managing of medical waste can improve the classification of medical waste in NICU, significantly improve the compliance of all kinds of health care workers to the standard handling of medical waste.
